The first thing to do is to check if your power wire actually has power to it. Do this with a test light or a multimeter. Given that the wire is powered, check to make sure your ground is good. Modern cars have so much plastic in them that grounds may be hard to find. The next step is to check the rig's fuse. Make sure the microphone is plugged in, too. If none of this helps, your radio needs repair or replacement.

I don't know how I copied and pasted so much sorry about that. But my question is I have orange and red wires with fuses and black wire without do I hook both red and orange to hot and black to ground?


it depends on what radio if you have a cobra 18wx style or maxon's, or a radioshack type the red is constant power 12v, orange is a switched 12v.. IE key like a stereo, and black is ground. if you have a 25 or 29 ltd types or exports they only have 2 wires red 12v and black ground. but you do find some power cords that have all three, and the orange on the 25 / exports are not used.

Schematics for a cobra 148 NW


Most units do NOT allow modulation adjustment as any more than 90-100% modulation causes adjacent channel signal "Splatter" therefore is subject to restrictions, hence generally that is locked. Also there really is no reason to have more than 100% modulation..as well ... why? I would suggest a voice/speech "Compressor" would be more suited.

We have a Cobra 148 nw st Sound Tracker When


It could be..
Final blown : worst case
bad mic : try another one
CB/PA switch on PA instead of CB
CB/WX swithc on WX instead of CB :you cannot transmit on weather.
Broken wire on mic jack.

Try the mic and switches first, and if that doesn't help you may need to take to tech. You can find one at a cb shop usually at truck stops.

Im looking for a plug to put in a wall socket and im trying to use an older cobra29 cb radio. Can you help?


Hey AlexJacob

a mobile cb radio like the cobra 29 requires 12V DC, to plug the radio into the wall you need a Power Supply. A small 5 amp power supply will help you. Their is no plug that goes Directly from a Mobile CB rado into a wall. You will need to plug a power supply into the wall, Then take the power chord (red and black with 3 prong [o oo] and connect red to red on the power supply and black to black on the power supply. Unfortunatly a cheap power supply will be $50+ check your local radioshack
